But who do you say that I am? asks Jesus at the decisive turning point in the Gospel. Simon Peter answers correctly at first but is soon corrected when he protests the revelation of the Cross. Christians in every age are called to confess the right faith in Jesus, who suffered, died, and rose for our salvation. Our own period is beset by a crisis of faith in Jesus, which has had manifold deleterious effects on our lives, our Christian communities, and our world. For the sake of addressing this crisis, the Aquinas Center for Theological Renewal at Ave Maria University and the Thomistic Institute of the Pontifical Faculty at the Dominican House of Studies cosponsored an international conference that took place at Ave Maria University under the title Thomas Aquinas and the Crisis of Christology. Beginning with a gripping foreword by Archbishop J. Augustine Di Noia, OP, of the Congregation for the Doctrine of the Faith, this volume gathers together several of the excellent conference presentations given by scholars working in North America, South America, Europe, and Western Asia. These studies consider both formulations of who Christ is and of how we are under his judgement. With help from Thomas Aquinas and the Thomistic tradition, this work engages today's crisis of Christology as seen in multiple theological topics and offers models of faith to answer Jesus' question for ourselves, "But who do you say that I am?"
